I have learned, the hard way, over the past 25 years of owning a home. Owning small engine tools are fun, but can be costly. In Houston, we are always having power outages, and we use our Generators, once a year, for extended periods. Over the years the carburetor get plugged up. This is expensive. Same goes for my Chainsaws, Leaf Blowers, Weed Trimmer, Pressure Washer, and Lawn Mower. Even if you take care of everything, the Ethanol gas tears up the Aluminum Carbs. Taking these to small engine repair places, can cost a $100-$250 each time, to clean and get them running. No More Paying These Repair People. Now, with just a few small tools, I replace the Carburetor, with a new one, for between $10-$18, and they come with a new spark plug, air filter, gaskets, fuel lines, priming bulbs. Usually they are extremely easy to put on, and run great, right from the start. Amazon or Ebay, is all the searching you need. If you are less mechanically inclined, YouTube has all kinds of people showing your exact model, and repair, step by step. Doing this has saved me a lot of money, and the need to buy replacement equipment. Good luck. Let me know if this helps.
